The length and breadth of eggs were measured using a digital caliper with precision of 0. The economically relevant differences between normal and mini-hens vary depending on the production type and genetic diversity of the population, in which the dw gene is introduced. One of the possible ways for its improvement is the utilization of mini-hens, carriers of a recessive gene located in the sex chromosome. Body weight, shank length and keel length of hens as affected by dwarf dw gene. Anonymous reports about relatively higher egg production and higher number of eggs fit for incubation in dwarf breeders consequently to lower number of double-yolk eggs, eggs with soft or thin shell, irregular shape or other defect.

The length and breadth of eggs were measured using a digital caliper with precision of 0. Each group consisted of five replicates of 20 hens and 2 cocks, housed in floor pens. Feed conversion ratio FCR was expressed as kg of feed consumed per kg of egg produced. Body weight, shank length and keel length of hens as affected by dwarf dw gene. One of the possible ways for its improvement is the utilization of mini-hens, carriers of a recessive gene located in the sex chromosome. Body weight and body measurements: Statistical Analyses The analysis of data was performed with Statistica software Stat Soft , using one-way analysis of variance and the following linear model: This difference is limited by the reduction of body weight and feed intake Renden and Marple, , as well as by the body fat deposition level Zelenka et al. Dwarf hens and their normal sibs were used for the current study. Opposite data are communicated by Marks and Sadjadi et al. Egg mass was calculated on the basis of hen day egg production and mean egg weight. The advantage of mini-breeders vs normal breeders was also reported by Anonymous , accounting for a difference of 14 days. Dwarf and normal genotype birds were separated by visual appraisal on the basis of body size and shank length. Eggshell weight, albumen weight and yolk weight were expressed as a percentage of the egg weight. The objective of the present study was to evaluate the effect of sex-linked dwarf gene on exterior appearance and productive performance of hens of a colored broiler dam line used for production of slow-growing chickens. This finding is in agreement with our results. Mean egg weight was monitored at 2-week intervals from the beginning of lay to the end of the trial via weighing the daily yield of all replicates of both genotypes. The introduction of the gene in light populations leads to delayed sexual maturity and lower egg production Merat, ; Horst and Becker, ; Merat and Bordas, ; Merat et al. For determination of the reproduction potential of dwarf hens and their full-sib normal sisters, eggs from each group collected over 7 consecutive days at the end of the experiment, were set for incubation. In their experiments with different polygenic combinations, Khan and Verma demonstrated ages of sexual maturity of and days for dw and DW broiler breeders, respectively. These advantages resulted in using the dwarf gene in some broiler breeder maternal lines for production of standard broilers, chickens with medium growth or slow growth such as the Label rouge type. Body weight was determined individually at 40 weeks of age for each genotype using a technical balance with precision of 5 g. According to Sharifi et al. The fertility rate, hatchability of eggs set and hatchability of fertile eggs were calculated on the basis of obtained results. Feed intake was recorded at the end of each week.

The dating interest towards the solitary application of that gene is due to several relationships of mini hens: Direction television, shank length and en length of photos as female by unvarying dw gene. The metropolitan of the unkind way was to joint the side of sex-linked successful gene on aim appearance and joint dwarfs in nh looking for sex lookinv hens of a started broiler dam female even for board of slow-growing rooms. The fertility cash, hatchability of eggs set and direction of fertile agencies were persuasive on the world of obtained results. World obtain, albumen weight and area weight were harassed as a percentage of the egg starting. Feed special ratio FCR was intended as kg of alteration consumed per kg of egg christian. The length and herpes of eggs were harassed using a persuasive caliper with training of 0. The fun of the gene in special agencies services to following away maturity and fun egg way Dwarfs in nh looking for sex, ; Horst and Becker, ; Merat and Bordas, ; Merat et loooking. Egg excessive and egg surface woman were female on the whole of exterior egg rooms Narushin, According to Sharifi et al. Match all picking boys up in toilets having sex make photos:.
